How is it an opinion piece? If you called it a bait-and-switch I might agree, since it starts off criticizing the performance of serverless architectures in general, and proceeds to critique the performance of one specific serverless architecture. But that critique uses the scientific method, and their conclusions appear to be reasonably well argued, so long as you substitute “Lamda + DynamoDB/S3” for “serverless”. What am I missing?
